Nail has finished running and is still receiving messages.

This is the same reason that WeChat can still receive information after exiting.

You can modify it in nailing settings and modify it to receive messages without reminding. Now that the nail has quit the group chat, it is normal that the information before this can be displayed normally. If you can still see the group chat information after quitting, then the system is not normal. So the information platform in the station misses you. For convenience, if you can view it normally, a short message will be sent for you to view.
